Practical application of active premagnetization in transformerless DC/DC converters
(2023-05-17)
Magnetic devices are used in almost every power electronic system. Therefore, their purpose and with that their requirements can vary in a wide range. The consequence is a large number of options regarding the priority of optimisation. In this work, the focus is on reducing the volume or weight of inductors in transformerless DC-DC converters. Active prmeagnetization is choosed as an optimisation approach. The technique enables an operation of the DC-DC-converter in the Triangular Current Mode (TCM), whereby ...

Numerical simulation of a sub-wavelength plasmonic THz antenna for bio-sensing applications
(2023)
In the past decades, bio-sensing has become a steadily growing field in the life-sciences. Popular subjects of investigation are proteins, which for instance mediate intra-cellular transfer of substances and thus are attractive drug targets. They are also responsible for the occurence of degenerative diseases such as Alzheimer’s disease and the Creutzfeld-Jakob disease. Examining proteins to uncover their fundamental properties and behavior is important in order to advance modern health care and medicine. One way to ...
